Kennametal 6388753 Replaceable Drill Tip 0.5156 in KCP15A

Product Description

The KENNAMETAL 6388753 is a replaceable drill tip designed for use with compatible modular drill bodies in machining operations on steel and cast iron. Built to the KTFSS series standard, this tip features a solid carbide construction in a fine grain grade KCP15A with a PVD-applied AlTiN coating for heat and wear resistance. The 180-degree point angle and HPG insert geometry promote stable entry and clean hole finish. It is installed and used by machinists, tool-and-die technicians, and CNC operators working in production or job-shop environments.

This replaceable tip is suited for drilling operations in steel and cast iron workpieces, including inclined exit surfaces and stacked plate configurations. The helical flute design and regular spiral type support chip evacuation during these demanding applications. With an insert seat size of P and a clamp-style holding method, it mounts to compatible KTFSS-series drill bodies. Two flutes and two margins provide consistent cutting geometry without through-coolant capability.

Key Features

• Solid carbide construction with fine grain KCP15A grade for toughness and edge retention
• AlTiN coating applied via PVD process for elevated-temperature wear resistance
• 180-degree drill point angle with HPG geometry for stable, accurate entry
• Helical flute with regular spiral supports chip flow in steel and cast iron
• Rated for inclined exit and stacked plate drilling applications
• Clamp-style retention in KTFSS insert seat size P drill bodies

Compatibility

Designed as a replaceable tip for KTFSS-series modular drill bodies accepting insert seat size P. Compatible primary workpiece materials are steel (ISO material code P) and cast iron (ISO material code K).

Installation Notes

Replaceable drill tips of this type are installed and changed by machinists or CNC operators following machine lockout and spindle-stop procedures. Seat surfaces on both the tip and the drill body should be inspected for chips or damage before seating the new tip. Follow the drill body manufacturer torque specifications for the clamping screw — do not use values not supplied with the tool body documentation. Confirm proper seating and runout before returning the tool to service.
